The invention relates to the technical field of road equipment, and discloses an air pressure controlled deceleration strip which comprises a box body embedded into the ground, a pressing block is movably connected to the upper end of the box body, a high-pressure air chamber is arranged at the bottom of the box body, a supporting plate is arranged at the top of the high-pressure air chamber, and an inflation bag and a supporting bag are arranged between the pressing block and the supporting plate. According to the air pressure controlled deceleration strip, whether the pressing block can be compressed or not is determined according to the wheels of the front wheels, when the vehicle passes at a low speed, the pressing block can be compressed, influences on the vehicle passing at the low speed are reduced, barrier-free passing of the vehicle is guaranteed, when the vehicle passes at an overspeed, the pressing block cannot be compressed, the vehicle jolts greatly, the intention of overspeed of a vehicle owner is lowered, and the vehicle speed is limited; the rear wheels of the vehicle are only hindered, the deceleration distance of half of the vehicle length is increased, the response time is prolonged, the probability that the speed cannot be reduced in time is reduced, meanwhile, the probability that the vehicle is out of control due to the fact that the rear wheels fly up is reduced, and safety is improved.
本发明涉及公路设备技术领域，且公开了一种气压控制的减速带，包括嵌入地面的箱体，所述箱体的上端活动连接有压块，所述箱体的底部设有高压气室，所述高压气室的顶部设有支撑板，所述压块和支撑板之间设有充气囊和支撑囊。该气压控制的减速带，根据前轮的车轮决定压块是否可被压缩，在低速通过时，压块可被压缩，减少对低速通过车辆的影响，保证其无障碍通行，而车俩超速通过时，压块不可被压缩，使车辆发生较大的颠簸，降低车主超速的意愿，限制车速，其次，只对车辆后轮产生阻碍，增加了半个车长的减速距离，增加了反应时间，降低来不及降速的概率，同时，后轮飞起使车辆失控的概率降低，降低了车辆失控的概率，提高安全性。
